Planet Name Generator
Generate names for planets and worlds that feel alien, ancient, or lived-in. Pick a genre and planet type — each name comes with atmosphere and mythology attached.
Tips for naming planets in your story
Keep it pronounceable
Even alien planet names benefit from a rhythm readers can follow in their heads. Avoid consecutive consonant clusters unless deliberately writing something unpronounceable — and even then, give readers a nickname.
Match the environment
An ice world with a name full of flowing vowels feels inconsistent. Use the Planet Type selector and the Notes field to anchor the phonetics to the environment — 'harsh', 'cold', 'ancient'.
Think about who named it
Planets named by their own inhabitants sound different from those named by outside explorers. A colonial designation might be a catalogue number; an indigenous name might carry millennia of meaning.
Use the meaning for your lore
Each name comes with a short note. A planet whose name means 'the eye that never closes' immediately has mythology attached. Build on it.
Frequently asked questions
How does the planet name generator work?
The AI generates names that feel authentic to your chosen genre and planet type. Each name comes with a short note evoking the planet's atmosphere, environment, or mythology.
What does the planet type option do?
Selecting a type — rocky, ocean world, ice, artificial, etc. — nudges the AI toward names that suit that environment. Ocean worlds tend to get flowing, liquid-feeling names; desert worlds get harsh, dry phonetics.
Can I use these names in my book or game?
Yes, completely free. All generated names are yours to use in any creative work, commercial or otherwise.
How do I make a planet feel alien but still memorable?
Use the Notes field with cues like 'unpronounceable by humans' or 'the ancient name, hard consonants'. Pair with a planet type for tightly scoped results. The best sci-fi planet names are short, distinct, and just slightly wrong.
